yeah I'm not reading 5 pages, but I will weigh in and I know much of this has already been said:
The rental contract may not be fair, but by signing on the line, you agree to it. Enterprise personnel are trained to describe the contract before getting signatures - in my experience, this is always done (even for frequent renters). Yes, Enterprise is closed from noon Saturday until Monday morning at 7:30am (typically). You are able to 'drop-off' the vehicle while they are closed, but until the employee signs off on the vehicle, post-inspection, the vehicle remains in the care and control of the renter (and if she places the keys in a drop-box, that's akin to leaving the keys on her kitchen counter - it's still in her control). This is clearly stated in the contract.
No, Enterprise is under no duty to have cameras covering its lots. It may be intelligent, or even something their insurer would like, but it is not their 'duty'.
No, the contract isn't 'unfair'. She had the option of returning it during business hours for no additional cost. You cannot choose a rental period to end during non-business hours, so she was paying for the car until Monday anyway. To drop it off while Enterprise is closed is a risk assumed by the consumer, and it's a stupid risk.
This is as clear as day. She is liable, and no media publicity should or will be able to save her. I hope Enterprise litigates this all the way through to trial, wins, and gets a cost award paid to them by the renter.
Boo me all you want, but could someone applaud me to balance it out? thanks
